Starved Rock Country Marathon

The Starved Rock Country Marathon takes place in May across Ottawa's flat road course, making it a straightforward effort without significant climbing to manage. The entirely road-based surface means consistent footing and predictable pacing conditions throughout the 42.2km distance. With zero elevation gain despite the gently rolling character, this is a course built for chasing a strong time rather than navigating technical terrain or steep grades. The May timing offers reasonable weather conditions for distance running in the midwest, though you'll want to check the specific forecast closer to race day. If you're targeting a personal best or prefer races without elevation surprises, this one delivers a no-nonsense marathon experience.
